Thanks again, that really helps.
So is the following correct to be able to use my db connection in my
controllers and models. Will this work correctly with preforking?
has db {
return App::Schema::connect(...);
}
$self->helper(db => sub { $self->app->schema });
$self->helper (model => sub { state $model = App::Model::Name->new(db =>
shift->db) });
